Automobile trunk lock mechanism(antitheft device)

ABSTRACT

General consideration of the present invention is to provide a device which would prevent the unauthorized opening of an automobile trunk lock without the use of a key. The device is fashioned to conform to various automobile trunk lock designs. The device offers protection by incasing the vulnerable areas of the lock, which if disturbed could result in the trunk&#39;&#39;s opening thus defeating the lock&#39;&#39;s purpose. The device is readily and economically fabricated from sturdy and durable material. The device requires no special care and no special knowledge for use by the user.

Wolfe [57] ABSTRACT 1 Claim, 3 DrawingFigures AUTOMOBILE TRUNK LOCK MECHANISM (ANTI-THEFT DEVICE) Generalobjects of the present invention are to provide protection to thepresent automobile trunk lock mechanism utilizing the present lockapparatus; developing a device which is of simple construction andreadily and economically fabricated and assembled on a mass productionbasis; is sturdy and durable, being capable of a long service life ofsevere usage; can be employed in all trunk locks offering protection toall excessable points where forced entry may be attained. The device canbe manufactured to fit the various models of automobile trunk locks. Theease of installation of this device permits ready conversion to make itavailable to all types of automobiles who have presently locks whichoffer no protection from forced entry. The objects of the applicantsinvention are:

1. To provide a device which will offer protection to points on the lockmechanism which will help to jar and otherwise defeat the locks purposewhen entry is desired without the use of a key.

2. To provide a device which is easily patterned to fit in manyautomobiles utilizing-the present turnk lock apparatus.

3. Another object of the present invention is that it involves nospecial care and no special knowledge for use by the user.

4. It is our aim to provide a device that is constructed of durablematerial; a minimal of parts without the complication of assembly;without the need to alter many types of automobile trunk lock systems.

For a fuller understanding of the nature and objects of the inventionreference should be had to the following detailed descriptions taken inconnection with the accompanying drawings in which:- 1

FIG. 1 is a perspective view of a trunk lock as it ma be incorporated inmany automobile trunks in different variations.

FIG. 2 is a perspective view 'of the sleeve which surrounds the stem.

FlG. 3 is an alternate form of a sleeve.

in FIG. 1 numeral 1 refers to the lock. It is in and around this areawhere forced entry is attained, by whatever means, causing distrubanceof surrounding area 2.

Tumbler housing 3 connects to the lock stem 5, this further continuesand turns in the latch opening 6 in the latch housing 7. Sleeve 4completely surrounds lock stem 5 and the latch opening 6 and all othervulnerable points which might fall herein. It is in this way thatprotection can be given to the trunk lock to prevent unwarranted openingof locked trunk without a key.

The invention accordingly comprises the features of construction,combination of elements and arrangement of parts, which will beexemplified in the construction hereinafter set forth and the scopeofthe invention will be indicated in the claims.

It will thus be seen that the objects set forth previously, among thosemade apparent from the preceding description, are efficiently attainedand since certain changes may be made in the previous construction anddifferent embodiments of the invention could be made without departingfrom the scope thereof it is intended that all matter contained in theprevious description or shown in the accompanying drawings shall beinterpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed including all statements of the scope of the invention which,as a matter of language, might be said to fall there between.

Having described our invention, what we claim as new and desire tosecure by Letters Patent is:

1. An automobile trunk latch mechanism for a pivoted led on anautomobile provided with a cylinder lock, a lock housing and a latchmechanism mounted on the exterior of said automobile to lock saidpivoted lid, a stem extending from the lock to an opening in the latchmechanism coherein rotation of said lock and stem releases said latchmechanism, the improvement comprising, a sleeve constructed of a durablematerial mounted on the rear of the housing incasing said stem and theopening in said latch mechanism, whereby said sleeve prevents access byunconventional entry around said lock housing to said stem and samdopening to operate the latch.

It is certified that error appears in the above-identified patent andthat said Letters Patent are hereby corrected as shown below:

Column 1, line 23, "turnk" should read trunk same column 1, after line31, insert the following: A more specific object of the presentinvention is that it provides a devicewhich can allow the.maximumprotection from theft or any other forcible entry of openingof'the trunk lid, without the use of the locks key, when the said trunklid is in the closed position,

The invention offers protection to the trunk lock stem by incasing itfrom being tampered-with, in whatever manner, which might defeat thelock's purpose when in the closed position and result in the opening ofthe trunk lid. p

A further object of this device, other than the protection of the trunklock stem, is that it also incases the latch mechanism entry hold (thepoint whereby the tumbler stem turns and opening. of, the latch isinitiated) This is covered by the device preventing probes fromv beingplaced that might bypass the tumbler stem mechanism and trip the latchhole thus defeating the lock's purpose. 1

This device further prevents the complete lock from being pushed'inwardby creating a barrier which surrounds the delicate components offeringadditional rigidity to the lock. 7

This-invention offers protection to automobile trunk locks in a mannerwhich up to now has not'been utilized or discovered.
